SPECIFICATION forming part of Letters Patent No. 457,265, dated August4, 1891.

Application filed January 31, 1891. Serial No. 379.758- (No model.) i

1'0 all whom it may concern.-

Be it known that we, J ULIUs FRELLOEHR,

of the city, county, and State of New York, and LOUIS TISCH, of Hoboken,in the county of Hudson and State of New Jersey, have invented a new andImproved Knitting-Machine, of which the following is a full, clear, andexact description.

The invention relates to machines for forming knitted fancy trimmings;and its object is to provide a new and improved knitting machine whichis simple and durable in construction, very effective in operation, andrequires no Jacquard mechanism to control the pattern of the fabric.

The invention consists of a series of pins acting on thethread-guidebars to reciprocate the same.

The invention also consists of certain parts and details andcombinations of the same, as will be hereinafter fully described, andthen pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of theimprovement with parts in section. Fig. 2is a front elevation of the same. Fig. 3 is an end elevation of the samewith parts in section. Fig. 4 is a transverse section of the same on theline or a: of Fig. 1. Fig. 5 is an end elevation with parts in sectionof the locking device for the chain carrying the pins. Fig. 6 is asectional rear view of the same on the line y y of Fig. 5. Fig.7 is aface view of the cam and bar carrying the needle-bar. Fig. 8 is a faceview of the gear-Wheel and crank-pin for reciprocating the needle-bar,and Fig. 9-is an enlarged perspective view of one of the chainlinkscarrying the pins.

The improved knitting-machine is provided with a suitably-constructedframe A, on one end of which is mounted to turn in suitable bearings thetransversely extending main driving-shaft 13, provided with fast andloose pulleys connected by belt to suitable machinery for imparting arotary motion to the said shaft B. On the latter is secured a bevelgear-wheel B, meshing into a like gear-wheel B secured on one end of ashaft B extending longitudinally and mounted to turn in suitablebearings secured on the main frame A at or near the rear, as is plainlyshown in Fig. 1. On the other end of the shaft 13 is secured a bevelgear-wheel B meshing into a like gear-wheel B secured on atransversely-extending shaft B, mounted to turn in suit-- able bearin gson the end of theframe A, op posite the end on which the shaftB ismounted. The bevel gear-wheels B, B B and B are so proportioned that theshafts B and B make one revolution to each revolution of thedriving-shaft B.

The longitudinal shaft B is connected by a mechanism,presently to bedescribed,with the needle-bar O, carrying the knitting-needles D, onwhich the fabric is formed. The

needle-bar O receives a reciprocating motion from the shaft B and ismounted to slide laterally in-suitable bearings A, formed on the ends ofthe main frame A. The needlebar O is rigidly connected near its endswith two rearwardly-extending bars 0, fitted to slide at their rear endsinbearings A erected on the main frame A. Each of the bars 0' isprovided with a cam O (see Fig. 7,) provided 'with an L-shaped slot 0engaged by a pin O projecting from a plate 0 held adjustable inguideways 0, formed on one face of agearwheel 0 The plate 0? is fastenedin place on the said gear-Wheel O by a set-screw O screwing in the plateO and against the face of the gear-Wheel 0 as plainly shown in Fig.

8. The two gear-wheels O are secured on longitudinally extending shortshafts 0 mounted to turn in suitable bearings 011 the main frame A, thesaid shafts 0 being located directly above the shaft B previouslymentioned. The gear-wheels O are in mesh with corresponding gear-wheelsB secured on the shaft B so' that when the latter is rotated thegear-wheels B impart a rotary motion tothe gear-wheels O and the latter,by their crank-' pins 0 engaging the cams O impart a sliding motion tothe bars 0, and consequently to the needle-bar C and theknitting-needles D.

Into the knitting-needles D pass the binding-threads E, guided to thesaid needles by guide-bars F, through which pass the saidbinding-threads. The eyed guide-bars F for the said binding-threads Eare secured to and roo project from a longitudinally-extending rod F,provided on its ends with trunnions F mounted to turn and to slidelongitudinally in suitable bearings formed on the ends of the main frameA. On the top of the rod F and near its front edge is arranged alongitudinally-extending round rod F over which pass the threadsprevious to entering the eyes of the guide-bars F.

The binding-threads E carry the usual weights E and pass over thelongitudinallyextending rods E and E secured in arms E mounted to turnon studs E secured on the ends of the main frame A. The arms E arelocked in place by nuts E, screwing on the said studs E and abuttingagainst the arms E so that the rods E and E are held inproperpositionafterthe armsE areadjusted that is, by turning the same onthe studs E and then locking the same in place by the nuts E Thebinding-threads, after passing over the lowermost rod E pass under a rodE extending longitudinally and held in the lower part of the main frameA. The threads E come from the spools E held on vertical spindles Earranged vertically and secured on aboard supported in the lower part ofthe main frame A. The weights E are preferably hung onto the threads Ebetween the rods E and E so as togive the threads the proper tension.

To the knitting-needles D also pass from above the pattern-threads G,also passing over a series of longitudinal rods G, arranged in suitablestandards erected on the main frame A directly above the needles D. Thepattern-threads G unwind from spools G arranged horizontally on asuitable spool-frame G supported on the rear end of the main frame A.The pattern-threads G, previous to passing to theneedles D, pass throughtubes H, arranged above and in front of the needles D, between thelatter and the eyed threadguide bars F. Each tube II is supported by anarm H from thread-guide bars 1, arranged longitudinally and fitted toslide in suitable bearings A formed on the ends of the main v frame A.One or more guide-bars I may be employed. As shown in the drawings, fourof the said guide-bars are employed. The arms H are rigidly secured onthe rear threadguide bar I. The other three thread-guide bars I carrythe sleeves H fitted to slide longitudinally and held adjustably thereinby set-screws H, to which sleeves are attached the arms H of the tubessupported by the said three bars I. The arms H on the rear thread-guidebar I are close together, so that a desired number of threads can bepassed through the corresponding tubes to form the groundwork of thefabric. The other three thread-guide bars only carry a few sleeves andcorresponding tubes for the threads necessary to produce theconfiguration of the pattern. The thread-guide bars I are caused toslide longitudinally by a special mechan ism, made in two identicalparts J and J, lo-

cated at the ends of the machine and actuated from the shafts B and Brespectively.

Each of the mechanisms J and J is provided with sets of pins K K,respectively, each set containing as many pins as there are thread-guidebars I. Each set of pins is mounted to slide longitudinally in a link Lof endless sprocket-chains L and L, passing over sprocket-wheels N andN, secured on a longitudinally-extending shaft N mounted to rotate insuitable bearings, arranged in the main frame A above the needle-bar O,as is plainly shown in the drawings. The center of the shaft N is in ahorizontal plane with the center of the thread-guide bars I, so thatwhen one of the links L of the said chains L and L stands in ahorizontal position at the front of the respective sprocket-wheel N orN. Then the respective pins K or K are in line with the thread-guidebars I, as is plainly illustrated in Figs. 1 and 3.

The shaft N receives an intermittent rotary motion from the shaft B andfor this purpose the shaft N? is provided with a ratchet-wheel N engagedby a spring-pressed pawl N pivoted 011 an upwardly-extending lever Nfulcrumed at its lower end on the main frame A. The lever N is pivotallyconnected by a link N with a second lever N arranged similarly to thelever N and acted on by a cam projection 13 secured on the hub of thebevel gear-wheel B A spring N presses the lever N rearwardly, so as tohold it in contact with the hub of the gearwheel B to be acted on by thecam projection 13 When the projection B on the revolving of the shaft Bpresses on the lever N then the latter swings forward and by the link Nimparts a similar motion to the lever N which, by the spring-pressedpawl N 4 engaging the ratchet-wheel N turns the shaft N such a distancethat the sprocket-wheels N and N move the next following link into ahorizontal position onto the front of the said sprocket-wheels. Thus thetwo corresponding sets of pins K and K always stand in line with thethread-guide bars I. The pins K in 'each set of pins may be of the samelength or of different lengths, or some of the same length and others ofdifferent lengths, as required by the pattern to be produced in thefabric.

Each thread-guide bar is acted on by two opposite pins in the respectivehorizontal links. The longest pin is acted on first by may move to theright, while the others move to the left, and the remaining bars may beat a standstill in case the opposite pins at the ends of the respectivethread-guide bars are IIS ' lugs L and L", of which the lug L is forkedto engage the lug 5 of the next following link. Pivot-pins L passthrough the engaged lugs L and L on adjacent links, the said pivot-pinsextending on the sides of the said forked lug L to engagecorrespondingly-shaped notches formed in the periphery of the respectivesprocketwheel N or N. (See Fig.3.)

The rear part'of each sprocket-chain is supported on a stud 0, held adjustably in a slotted bracket 0 secured on the main frame A. The innerend of each stud 0 passes through the transversely-extending slot 0 inthe bracket 0 and the said stud is secured in' place when adjusted by anut 0. (See Fig. 1.) The studs 0 are made transversely adjustable in thebrackets O for supporting longer or shorter sprocket -chains L or L.According to the pattern to be produced, more orless links are requiredin each sprocket-chain, as each set of pins carried by the respectivesprocket-chains forms one particular part of the design produced in thefabric. Hence if the design is greatly varied a larger number of linkswith corresponding pins K or K are necessary and required in the endlesssprocket-chains L and L. The sets of pins K and K are acted on at theirouter ends by striking-plates P and P, respectively, when the said setsof pins are in a horizontal position in the front of the sprocketwheelsN or N. Each of the plates P and P is of suffioient width to engage allthe pins in a link L The plates P and P are each secured on itsrespective arm P extending to the front of the machine and rigidlyconnected with two sliding bars P fitted to slide longitudinally insuitable brackets A arranged on the main frame A. Each of the arms P ispivotally connected with a lever P extending downwardly and having itsfulcrum on a bracket projecting from the main frame A, as is plainlyillustrated in Figs. 2 and 3.

Each of the levers P on the ends of the machine is pivotally connectedby a link P with a crank-arm P each when revolvingimparting a swingingmotion to the respective leverP*, so as to move-the striking-platePor Pforward and backward. The crank-arm P on the right-hand end of themachine is secured on the main shaft B, while the other crank-arm P onthe left-hand end of the machine is secured on the shaft B. The twocrank-arms on the shafts B and B are arranged in opposite directions, sothat the striking-plates P and P move simultaneously with each other andin opposite directions.

In order to cause a return or outward sliding motion of each set of pinsK or K, a secmoved into an angular tion to the lever Q,

0nd set of striking-plates P is provided, ar-

ranged on the inside of the endless sprocketchains Land L, and adaptedto engage the inner ends of the pins when the respective link is in anangular position, as illustrated in Fig. 3. Each 'of the striking-platesP is secured on a lever P pivotally connected by a link P with therespective lever P actuating the striking-plate P or P, respectively.When the lever P swiugs'inwardly on the rotation of the respective shaftB or B, then the respective striking-plate P or P moves in an inwarddirection to move the corresponding set of pins K or K onto the threadguide-bars I. At the same time the said lever P by the link P imparts aswinging motion to the lever P so that its striking-plate P swingsoutward to return the respective set of pins to an outward position onthe respective sprocketchain L or L. It is understood that thestriking-plates P act on the set of pins which had previously stood in ahorizontal position on the front of the respective wheel-N or N, and bythe rotation of the shaft N had been position, as is previouslymentioned, so as to bring its pins in line with the striking-plates P Inorder to prevent the pivot-pins L from becoming. disengaged from thelugs L or L a spring-plate L is provided, secured on each of the links Land abutting against one outer end of the said pivot-pin.

. In order to holdthe links L in a horizontal position on the front ofthe sprocket-wheels N and N, respectively, a locking device Q isprovided, (shown in detail in Figs 5 and 6,) and provided with a leverQ, extending vertically and adapted to engage with its upper end theunder side of the front end of the respective link L when the lattermoves into a horizontal position.

The lever Q is fulcrumed at Q on the bracket A the lowerend of the saidlever being' provided with a sidewise-extending arm Q slightly inclined,as shown in Fig. 5, and adapted to be engaged by a projection Q",secured on the respective shaft B or B5. WVhen the latter is rotated,the projection Q presses on the arm Q so as toimpart a swingingmowhereby the upper end of the said lever swings outward away from underthe respective link L This movement takes place previous to the rotationof the shaft N which actuates the sprocket wheels and chains, as abovedescribed. The respective link L is then free to swing downward, afterwhich the spring Q on the lever Qreturns the latter to its normalposition, so that the next link swinging into a horizontal positionagain rests with its outer end on the upper end of the lever Q.

In order to prevent sidewise motion ofeach link L at the time it standsin a horizontal position, two guide-arms Q are provided, secured on topof the bracket A and adapted to engage the sides of the respective link.

In order to hold. the thread-guide bars I in position during theknitting process, a locking device R is provided having averticallyarranged locking-bar R, pointed at its lower end and adaptedto engage notches I placed equidistant apart and formed in the top ofthe said thread-guide bars I and arranged to register transverselydirectly under the sharp edge of the locking-bar R. The locking-bar R ismounted to slide vertically in a bearing R secured on the main frame A.An arm R passes through a vertical slot in the said bearing R to engagethe bar R,so that when the arm R swings upward the bar R is withdrawnfrom the respective notches I in the top of the thread-guide bars I. Thearm R is secured on a shaft R mounted to turn in suitable bearings inthe main frame A, one end of the said shaft being provided with acrank-arm R pivotally connected by a link R with an arm R pivoted on themain frame A. The outer end of this pivoted arm R is adapted to beengaged by a cam R held on the shaft B", so that when the latter isrotated the said arm R is swung downward, so that the crank-arm R ismoved in the same direction, and the arm R swings upward to disengagethe locking-bar R from the threadguide bars I. A spring R is secured tothe crank-arm R so as to insure a return movement of the shaft R the armR and the locking-bar R after the cam R has disengaged the pivoted arm RThe binding-thread-guide bar F has a slight longitudinally-slidingmovement and a rocking motion. In order to accomplish the slidingmovement a device S is provided having an upright lever S, fulcrumed atits lower end at S to one end of the main frame A, the upper free end ofthe said lever abutting against one end of one of the trunnions F Afriction-roller S is held on the lever S, and travels on the peripheryof a wheel S secured on the shaft 13 and provided on one face with aprojection S adapted to engage the said friction-roller S so as to movethe lever S inwardly to shift the thread-guide bar F to the right. Thereturn movement of the guidebar F is accomplished by'a spring F coiledon one of the trunnions F and abutting with one end on one of thebearings of the said trunnion while the other end rests against thecollar F secured on the said trunnion. This spring F is pressed when thelever S swings inward, as before described, the spring serving to returnthe guide-bar to its normal position after the projection F has left thefrictionroller S A rocking device T for the thread-guide bar F isprovided with a bar T, secured to one of the trunnions F of the said barF, the outer end of the bar T being pivotally connected by a link T witha lever T pivoted at T on one end of the main frame A. The lever Textends transversely and is adapted to be engaged at its rear end by aprojection B secured on the shaft B When thelatter is rotated, thisprojection B raises the rear end of the lever T so that its front endswings downward, thereby pulling on the bar T, thusturning the guide-barF so that the eyes of the said guide-bar swing upward to lift the threadonto the needles. The return motion of the guide-bar F is accomplishedby a spring T connected at one end with the inner end of the bar T andwith its other end secured on the main frame A. (See Fig. 4.)

In order to hold the fabric in place below the needles D, alongitudinally-fixed bar D is provided, secured in the ends of the mainframe A. In front of this bar D is arranged a rod D secured to arms Dextending downwardly and pivoted at their lower ends on the ends of themain frame A. One of the arms D is connected with one end of a cord Dpassing over a pulley D held on one end of the main frame A, thedownwardly-extending part of the cord D supporting a weight D The latterhas the tendency to draw the arms D and the rod D inwardly, so as topress the rod D onto the front of the fabric to clamp the latter betweenthe bar D and the rod D The fabric afterward passes from the bar D andthe rod D onto a roller U, journaled in fixed hearings in the ends ofthe main frame A. A second roller U is arranged below the roller U andover which passes the fabric after leaving the roller U. The roller U isjournaled in arms U pivoted on the main frame A, and supporting at theirrear ends a weight U so as to press the roller U toward the roller U.From the roller U the fabric passes under a roller V and then around thecloth-beam V, on which the fabric is wound. The cloth-beam V is providedwith a pulley V over which passes a belt V also passing over a pulley Uheld on the roller U, as is plainly shown in Fig. 3. The roller Ureceives an intermittent rotary motion from the shaft B the said rollerbeing provided for this purpose with a ratchet-wheel U engaged by aspring-pressed pawl U on a lever U fulcrumed on the axis of the rollerU. The lever U extends rearwardly over the shaft B which latter isprovided with a projection U for raising the said lever U to cause thepawl U to impart an intermittent rotary motion to the ratchet-wheel Uand consequent ly to the roller U and the cloth-beam V. The projection Uis so arranged that motion is imparted to the roller U and thecloth-beam V aft-or the knitting has taken place by the needles D.

The operation is as follows: When the several parts are in position andthe main shaft B is rotated, then motion is imparted to the severaldevices. The needle-bar-- (J receives a reciprocating motion, so thatthe needles D knit the binding-threads E with the pattern-threads G toform the desired fabric. The sets of pins K and K in the several links,and the sprocket-chains L and L, respectively, have previously beenselected in respect to their length to shift the threadand K. shiftedlongitudinally the locking-bar R that is, moving rearward-the respectivethread-guide bars I are shifted longitudinally by the respective set ofpins K or K being driven inward by the respective strikingplates P or P,it being understood that the i set of pins acted on are in a link whichstands in a horizontal position on the front of the sprocket-wheels N orN, respectively. By this shifting of the thread-guide bars I theposition of the respective pattern-threads G, passing through the tubesH supported from the said thread-guide bars I, is changed relative tothe needles D, so that at the next outward movement of the needles otherthreads are knitted with the binding-threads E, according to the fabric,the design of which is represented by the different sets of pins K Assoon as the guide-bars I are moves downward to engage the respectivenotches in the bars I, to lock the latter in place. Previous to thestriking-plates P and P, operating on their respective sets of pins Kand K, the said locking-bar R is moved upward to unlock the thread-guidebars I, as previously described.

It is understood. that the several movements of the devices mentionedare so timed as to produce the desired result.
